AUTOMATIC TRAIN-STOP.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed February 16, 1916. Serial No. 78,766.

To all whom it may concern:

Be it known that I, ALFRED EDWARD HAS- ELTINE, a citizen of the UnitedStates, re siding in the county of Greene and State of Missouri, at R.F. D. No. 7, Springfield, Missouri, have invented a new and usefulAutomatic Train-Stop Used Upon Railroads, of which the following is aspecification.

This invention relates to automatic train stops by which a train will bestopped upon passing a semaphore set at danger position.

The object of the invention is to provide an automatic train stopcomprising a head having a trip portion, and pivotally supported uponlevers which levers are pivotally connected intermediate their ends on atrack fixture. The ends of the levers are connected with signaloperating means,-

whereby in the actuation of the signals, the head is automaticallyraised in position to intercept the trip element on the traveling train,and through such element operate the stopping means.

In the drawing Figure 1 is a view in elevation, illustrating theoperation of the device.

Fig. 2 is a plan View of the device in position on a track.

Fig. 3 is an end elevation of the device, the parts being in operativerelation in full lines and in inoperative relation in dotted lines.

The mechanical device forming the subject matter of this application is.designed to 'be operated by and with a signal device 1, so that whenthe device is set, as when the signal is at danger, a train will bestopped, or the brake thereof set.

The structure comprises levers 3 and 4, pivotally mounted intermediatetheir ends on blocks secured to the road bed, the lower ends of thelevers being connected to a rod 2. The rod 2 is connected to or operatedby the signal means 1, so that the levers are operated as the signal israised or lowered.

A head 5 is connected to the upper ends of the levers 3 and 4. Thishead, when elevated is in a position to be engaged by a rod 6, dependingfrom a valve 7 of the train'air pipe system 8. The engagement of the rod6 with the head 5 acts to operate the valve, 7 to set the brake. It willbe noted thatthe connection of the rod 6 with the head 5, is at a pointon the latter interposed between the levers 3 and 4, thereby resisting abraking strain incident to such contact.

Having thus described the invention what is claimed as new is automatictrain stop comprising a head, levers pivotally supporting the head andconnected to the latter on opposite side of a trip contact portion ofthe head, said levers being pivotally connected intermediate their endson a track fixture, the ends of the levers remote from the head beingconnected to an independent element, whereby in the operation of suchelement there is occasioned a simultaneous movement of the head.
